401 Receiver
1. Rackmounting the Receiver
The 401 receiver is supplied with RACK EARS (1) which can be attached with the screws
provided on the front of the side panels to enable rackmounting.
(Note: Do not mount the receiver in a rack directly above an amplifier or other source of
high heat – this could degrade the performance of the 401. Always ensure adequate airflow
and heat dissipation in any rack configuration.)
2. Powering the Receiver
Plug the 12V AC/DC ADAPTER (2) provided into the DC INPUT JACK (3) on the back
of the receiver. Then plug the power supply into an AC outlet.
(Note: Any 12V DC source with 400mA capability can also be used.)
Turn VOLUME CONTROL (11) for all four channels counterclockwise to mimimum locat-
ed on the back of the receiver. Once the receiver is connected to a power source, press the
POWER SWITCH (4) to ON position. The TX LED INDICATOR (5) on the front panel
of the receiver will not light up until one or more of the four channels is receiving a signal
from your system’s transmitter.
3. Antennas
The ANTENNAS (6) assembly consists of two antennas. Connect antennas into the ANTEN-
NA JACKS (7) on the back of the receiver. Extend the antennas fully to obtain maximum
range. Position ANTENNAS (6) at 45 degrees from the horizontal; 90 degrees from each
other. For maximum range, it is always best to maintain a line of sight (no obstructions)
between the receiver antennas and the transmitter whenever possible.
4. Mute (Squelch) Adjustment
In normal operation, the MUTE CONTROL (8) should be set fully counterclockwise to the
factory preset minimum RF level of 1µV for maximum sensitivity. Doing so sets each
receiver for maximum range. However, in areas of high RF activity, the mute (or squelch, as
it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a
particular location. If, with the transmitter off, its corresponding LED on the receiver front
panel flickers or stays on, the MUTE CONTROL (8) should be turned clockwise until the
LED extinguishes. For each of the four channels, when the Mute is properly adjusted, the
corresponding LED will light only when the system’s transmitter is turned on. Turning the
MUTE CONTROL (8) too far clockwise will result in reduced range, but yield a quieter sig-
nal during dropouts or at the end of the operating distance range.
